Waterproof structure for a transmission cable

Abstract

A waterproof structure for a transmission cable includes a transmission cable which includes a transmission head and a connecting wire. The transmission head includes a plug segment and a neck segment. A sleeve has a through hole defined axially therethrough, and the sleeve is mounted to the plug segment of the transmission cable. Multiple ribs are circumferentially formed on an outer peripheral surface of the sleeve. Each rib extends outwardly from the outer peripheral surface of the sleeve. The ribs are spaced apart from the others. Each rib is deformed when subjected to pressure. When the transmission cable is inserted into a socket, any of the ribs can seal the socket interface according to the depth of insertion, so as to effectively prevent external moisture, liquids, and other contaminants from entering the socket.
